The Trigon Miniguard 100BD is a handset type, multi-number, telephone entry system for resident/visitor control. Visitors contact the desired tenant by entering a simple directory code gained from the built-in electronic directory. The resident then grants or denies access. The resident can utilize keyless entry by using the individually assigned access code entered on the Miniguard's keypad. TrigonLink programming software is available for direct RS232 interface or optional modem interface. The Miniguard 100BD has a capacity of up to 400 telephone numbers and up to 400 personal entry codes. It is constructed for rugged outdoor use, yet remains pleasant in appearance. Its long-lasting brush-finish stainless steel housing complements its thin design lines. A matching flush-mount trim-ring or lighted hood may be selected to add the right finishing touches to an installation. The Miniguard 100BD is equipped with valuable features and options that provide a wide range of guest and resident control options-doors, gates, security lighting, and more.
